San Diego  When asked recently if she feels like she has unfinished business in her role as district attorney, Bonnie Dumanis replied: “It’s a journey. There is no destination.”

Voters gave Dumanis four more years to chart that journey, giving her 55 percent of the vote in Tuesday’s primary election. By securing more than 50 percent of the vote, she avoided a November runoff with private attorney Bob Brewer or retired prosecutor Terri Wyatt, who got 35 percent and 10 percent of the votes, respectively.

While Dumanis may not be sure where she’ll end up, she is clear on where she’s going.

Her top priorities in her fourth term, which will officially begin in January, include an increased focus on human trafficking, elder abuse and cyber crime, topics she brought up frequently on the campaign trail.

• On human trafficking: “It’s a real issue here in San Diego and a rising crime, and one that’s second only to drug trafficking,” Dumanis said. “We need to work on helping victims, the young girls 12 to 14 years old, and … opposing the gangs who are using them and abusing them.”

The office prosecuted 43 people in 35 human-trafficking cases last year, a growing number as gangs capitalize on the sex trade. Dumanis has supported state legislation that streamlined human-trafficking cases in court and also participated in outreach and education campaigns to help victims.

• On elder abuse: “Looking at those in assisted living and other types of care provision, and try to prevent first but also prosecute.”

Dumanis announced in March a pilot project to prosecute neglect and abuse incidents inside care facilities, incidents that often go unpunished by state regulators, following a joint investigation by U-T San Diego and CHCF Center for Health Reporting.

• On cyber crime: “Everything from identity theft to the Internet to crimes against kids and hacking. It’s taken off because technology has taken off.”

She said the elderly are especially vulnerable. The county recently created its own cyber crime task force, partnering with the District Attorney’s Office, Sheriff’s Department and other agencies.

Perhaps more urgently, Dumanis will also have to mend any rifts that were created as a result of the hotly-contested election that often put her on the defensive and saw prosecutors, defense attorneys and law enforcement officers taking sides.

Dumanis sent an email to her staff the morning after, acknowledging the “difficult election season.”

“Thank you for your perseverance during this disruptive time,” she wrote. “Your professionalism is what makes our office one of the best in the country.”

Dumanis declined requests for a post-election interview Wednesday.

Gang prosecutor Robert Hickey, president of the Deputy District Attorneys Association, said while election fever might have gotten heated at times, the vast majority of employees stayed out of the fray. About a third of the prosecutors in the association voted to endorse Brewer.

“My goal was to keep the office from getting fractured like what happened in 2002, and I feel like we did a good job,” Hickey said, referring to the bitter contest 12 years ago when Dumanis unseated then-District Attorney Paul Pfingst.
